Given numbers are 644, 172, 558, 383

The list of prime factors of all numbers are

Prime factors of 644 are 2 x 2 x 7 x 23

Prime factors of 172 are 2 x 2 x 43

Prime factors of 558 are 2 x 3 x 3 x 31

Prime factors of 383 are 383

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 644, 172, 558, 383

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(644, 172) = 27692

GCD(644, 172) = ( 644 x 172 ) / 27692

= 644 / 172

= 644

Step2:

LCM(4, 558) = 1116

GCD(4, 558) = ( 4 x 558 ) / 1116

= 4 / 558

= 4

Step3:

LCM(2, 383) = 766

GCD(2, 383) = ( 2 x 383 ) / 766

= 2 / 383

= 2

So, Greatest Common Divisor of 644, 172, 558, 383 is 1
